spm backend not detecting executable targets correctly

[natanrolnik]

Hey @jdx ! Huge fan of mise here, after getting to know it via Tuist.

I write some tutorials about tooling with Swift in SwiftToolkit.dev, and I wanted to show how mise can be useful to run Swift executables from remote sources.

I noticed the spm backend in mise is still experimental, but I think there's a regression, probably due to a change in Swift 6's swift package dump-package output.

When running:

mise use -g spm:swifttoolkit/[email protected]

I get the following output:

mise ERROR failed to install spm:swifttoolkit/[email protected]
mise ERROR No executables found in the package

I digged a bit into the spm backend source, and found these lines. I ran swift package dump-package in my repo, and I got "type" : "executable" instead of "type" : { "executable" : null } as described in the comments in the linked lines.

Please let me know if there's any info I can provide more 🙏🏻
